PAPER-MAKlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 689,400, dated December 24, 1901.

Application filed December 20, 1900. Serial No. 40,611. (No model.)

To all whom it may concern.-

Be it known that I, MARBLE D. KEENEY, a

citizen of the United States, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Paper Making Machines, of which the following is a specification. My invention relates to improvements in Fourdrinier and cylinder paper-making machines, and while designed more particularly for use in the making of tissue and other light papers may be employed to advantage in the manufacture of Fourdrinier and cylinder pa pers of all kinds.

It consists, first, in the provision of means for automatically delivering the web of paper from the first-press rolls to the second-press felt or apron and from the second-press rolls to the drier felt or apron, and thereby preventing breaks in the web intermediate of the first-press rolls and the drier or driers, and, second, in the peculiar and advantageous combined suction and blast rolls hereinafter described, and particularly pointed out in the claims appended.

In the accompanying drawings, Figure l is a diagrammatic view, partly in vertical section, illustrating a portion of a cylinder paper-making machine equipped with my improvernents. section illustrating one of the combined suction and blast rolls and the manner in which said roll operates to take the web of paper from a press-roll and deliver such web to a preceding felt or apron. Fig. 3 is a View, partly in elevation and partly in section, of the suction and blast roll, said view as compared with Fig. 2 being on a slightly-reduced scale and its sectional portion taken on the broken line 3 3 of Fig. 2. Fig. at is a front elevation of the suction and blast roll with the outer rotary portion of the same removed. Fig. 5 is a similar view illustrating that part of the stationary portion of the roll which is arranged contiguous to a press-roll.

In the said drawings similar letters of reference designate corresponding parts in all of the several views, referring to which A is a vat which ordinarily forms part of a cylinderpaper-making machine. B is aforming-cylinder therein.

0 C are the rolls of the first press.

Fig. 2 is an enlarged vertical Dis the first-press felt or endless apron, which takes around idler-rolls E and over the forming-cylinder and between the press-roll C after the usual manner.

F F are the rolls of the second press.

G is the second-press felt or endless apron, which takes around the usual idler-rolls H and between the rolls F and has its rear portion arranged adjacent to the first-press rolls 0.

I is a drier.

J is the drier felt or apron, and K K are my improved suction and blast rolls, the former being shown as arranged above the upper press-roll C and the latter in advance of the press-roll F. They may, however, be arranged in any manner with respect to their complementary rolls that is conducive to the purposes of my invention. The suction and blast rolls K K are similar in construction, and therefore a detail description of the roll K (illustrated in Figs. 2 to 5) will suffice to impart a clear understanding of both. The said roll K in the preferred embodiment of the invention comprises a stationary or fixed portion, which is mounted in any approved manner in a suitable frame or support, and a rotary portion which is free to be moved by contact with the press-roll, which may be driven by belt or friction from any other rotary part of the machine. The stationary portion is preferably made up of metallic heads a, a metallic cylinder 1), interposed between and connected by bolts 0 or other means to the heads and having a longitudinal groove cl in that portion of its poriphery which is contiguous to the adjacent press-r011 and also having the apertures 6,

preferably arranged in a staggering manner,

as best shown in Fig. 4, and the larger apertures f, which are also preferably arranged in a staggering manner, a pipe or conduit g, which preferably occupies the longitudinal center of the roll and is divided. by a partition h and provided at one side of said partition with one or a plurality of apertures 1}, which connect its interior with the interior of the cylinder 1 tubesj, which connect the interior of the pipe g at the opposite side of the partition h with the groove 61 in the periphery of the cylinder, an oil-reservoir in the form of a pipe k, which is interposed between the conduit 9 and the wall of the cylinder 1) and has its inner end closed and its outer end extended through one of the headset and connected to an oil-cup Z, and tubes m, which communicate with the oil-reservoir 7t and extend through and are suitably secured in the aperturesf of the cylinder and are adapted to receive wicks n. The rotary portion of the roll is made up of a foraminated metallic cylinder p, which snugly surrounds the metallic cylinder 1) of the stationary portion between the heads at thereof, and a cylinder q, preferably of rubber, which is vulcanized on or otherwise secured to the metallic cylinder 19, so asto turn therewith, and is provided with apertures in register with those of said metallic cylinder 19.

The oil-reservoir 7c is designed to be supplied with oil or lubricant through the cup Z, and the lubricant is conveyed by capillary attraction through the wicks n to the inner surface of the metallic cylinder 13 of the rotary portion, wherebyit will be seen that the said cylinderp and the cylinder 12 are thoroughly lubricated, and consequently movement of the former on the latter is rendered easy and frictional wear of both is reduced to a minimum. It will also be seen that the roll is adapted to hold a large quantity of lubricant in such manner that the same is not liable to be carried away or otherwise affected by the air passing through the roll.

The apertures e are preferably arranged, as shown, with reference to the direction of rotation of the rotary portion of the combined suction and blast roll and-the press-roll complementary to the combined suction and blast roll and are designed to permit a blast of air to pass from the interior of the cylinder through the registered apertures in the metallic and rubber cylinders of the rotary portion and blow the web of paper off the roll after the manner indicated by arrows in Fig. 2.

That end of the conduit 9 to the right of the partition h in Fig. 3 is designed to be connected with a fan or other blower or source of air-pressure, and the other endof the conduit, which is in communication with the groove at through the tubes j, is designed to be connected with a vacuum-pump or other device calculated to create a partial vacuum in the portion of the conduit to the left of the partition h in Fig. 3, andby the vacuum thus created the sheet or web of paper is drawn from the press-roll and held by the Vacuum to the suction-roll until thrown 011' by the air-blast. The groove (1 constitutes the receiving portion of the conduit that is adapted to be connected to a suction or vacuum-creating device.

In practice the rolls K K are arranged as shown in Figs. 1 and 2 with respect to their complementary press-r01lstl1at is to say, they are arranged with their grooves d contiguous to the press-rolls. From this it follows that as the web of paper passes under the rolls K K it will be taken off the pressrolls and held tight to the. exterior of the rotary portions of the rolls K K and carried around in the direction indicated by the arrow with the same. This is due to the suction through the grooves 01, tubes j, and pipes g of the rolls K K, and also to the fact that the outer cylinders g, being of rubber or other yielding material, cave when they con tact with the press-rolls, as best shown in Fig. 2, with the resultthat air is forced therefrom and the web of paper is caused to adhere to the periphery of the rubber cylinder. The web of paper is thus carried around with the rotary portions of the rolls until it is thrown off the same by the blast of air through the pipe 9 at the right of the partition h, the apertures 'i, the interior of the cylinders 12, and the apertures e. In either casethe web of paper is subject to the action of the blast through the apertures e and the apertures of the rotary portion in register therewith and is forced or delivered by the same in a gentle manner to the felts or aprons in advance of the rolls. This is advantageous, since it renders it unnecessary to handle the web of paper and prevents breaks in the web intermediate of the first-press rolls and the drier or driers.

-As indicated by arrows in Fig. 1 of the drawings, the two presses are run in a common direction. This is usual in the manufacture of tissue and other light papers on cylinder and Fourdrinier machines; but it is obvious that when heavy papers are to be made the second press will be run in the opposite direction. The second-press felt or apron is brought up close to the top roll of the first press in order to catch the sheet or web as it is forced off the roll K by the blast of air, this insuring the delivery of the web of paper to the second press without the aid of the attendant.

It will be appreciated from the foregoing that my improvements, while simple and in expensive, add materially to the efficiency of the cylinder and Fourdrinier, also the machines extant, especially when the same are to be used in the manufacture of tissue and other light papers; also, that my improvements are susceptible of ready application to cylinder and Fourdrinier machines at present in use, which is an important advantage. 1
